Steatite
GBC's Steatite (Proto-Enstatite, MgO Si02) Ceramic is ideal for high frequency, low loss, high voltage insulation.
Our L-3 Steatite composition is multi-component crystalline phases of the Magnesium-Aluminum-Silicate system group. With good mechanical properties, low loss electrical qualities, it is ideal for resistor forms, surge arrestors, standoffs, spacers, and coil forms. Steatite is easily fabricated to close tolerances and is much less expensive than Alumina ceramic insulators.
